The total current supplied from the Communication Unit to each I/O Unit (I/O Unit interface current
consumption) is 0.3 A max.
Mount Units on DIN rail (DIN 35-mm track: all Units).
Connect I/O Unit Connecting Cables and end connector.
Connect Communication Unit internal power supply (24 VDC --15%/+10%).
Connect I/O power supply (24 VDC --15%/+10%) for each Transistor Input/Output Unit and Relay
Output Unit.
Connect I/O power supply (24 VDC --15%/+10%) for each Analog Input/Output Unit and power
supply for each Counter Unit encoder, using a separate power supply from the above.
Connect I/O to each I/O Unit.
Set the PROFIBUS-DP address of the Communication Unit.
Set the Analog Input Unit and Analog Output Unit ranges and other specifications.
Connect the Communication Unit to the PROFIBUS-DP Master Unit using the PROFIBUS-DP
Communications Cable.
Turn ON the PC power supply.
Turn ON the I/O power supply to individual I/O Units.
Turn ON the Communication Unit internal power supply.
Configure all connected MULTIPLE I/O Units in de PROFIBUS-DP master.
Check the I/O Unit interface status.
Check the indicators on all Units.
The following indications are normal:
Communication Unit US indicator:
Communication Unit BF indicator:
TS indicators for I/O Units and Communicaton Unit: green ON
Check that the data for the I/O words allocated in the I/O memory of the CPU Unit of the PC is
being correctly read and written by the CPU Unit.
